Closed Structure: CASIL battery has unique structure and sealing technology effectively keep the battery from leaking so that the battery can work under various circumstances

Electrolyte Suspension System: The electrolyte inside adopts electrolyte suspension system combined of porous glass fiber materials and pole plates and the electrolyte is completely absorbed and accommodated. No silica gel or contaminated products are used. The incorporate design controls gas production and can guide 99% of the gas produced during float charging to re-combine

Low-pressure Valve System: All the CASIL batteries are equipped with safety exhaust valves, which automatically exhaust when the pressure reaches 0.98~196.1kpa, therefore, there is not too much gas stocked inside the battery.

High-quality Grid: The high-quality lead-calcium-tin alloy grid, whether used in float charging or recycling, or even through many times of over-discharge, keeps strong performance and long service life

Float Charging Life: CASIL high-performance series of batteries can be used for 2-4 years for float charging

decovery Role of Deep-discharge: CASIL battery can only recover its capacity by deep discharge
